So belts fine...tension on on side. Looser on the other..its groved..no codes...just. Did rad flush and all vacuum lines on the B5 engine...but driver side block in the front there's a cam shaft sensor...n inside there's...I dunno what holds belt n directs it..but car on...when it comes up. Before that front left guide or if its cam sensor still...it make. A rubbing flapping noise..I have it turn down n isolated the sound...Anything would help..Thanksss
